Other Parts Discussed in Thread: OMAPL138
Hi,
We encountered the DAC IC Vout having output voltage ramp up to maximum 2.4V intermittent. This behaviour can be seen in all the Vout but randomly occur. The DAC IC is controlled with OMAPL138 SPI lines with a level shifter (1.8V to 2.8V) in between . DAC IC is also supplied with 2.8V voltage. Notice at the scope plot below, Vout3 sometimes it's having the voltage goes up for 1.5s even when ther's no configuration happening. Would like to get advice on this.
Regards,
Leo
